Application October 26, 1944, Serial No. 560,410

(Cl. 23S-62) 1 claim. 1

This invention relates to railway ties and has for its object to provide a tie of relatively inexpensive structure and of greater durability than ties at present in use, and one upon which a rail may be quickly secured.

A principal object of my invention is to provide a railway tie so constructed that it will become impossible for rails seated thereon to spread apart or move relative to the length of the tie:

A further object of the invention is to provide a railway tie formed of a plurality of superimposed U-members, certain of which form seats for rail chairs.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a side elevational view of my rail- Way tie,

Figure 2 is a top plan view thereof,

Figure 3 is a sectional view taken on line of Figure 2,

Figure 4 is a perspective view of the tie partly broken away and the rail retaining chairs being removed,

Figure 5 is an end elevational view of the device,

Figure 6 is a detail perspective view of a pair of rail chairs shown seated upon a. rail flank, and

Figure 7 is a transverse sectional view of the body of the tie.

Like reference characters indicate like parts throughout the following speciiication and in the several views in the -drawings in which I0, indicates a tie formed in accordance with my invention which consists of an elongate U-shaped metal tie I I, having a flat bottom I2, and right angular side walls I3 and I4, beveled off at the outer ends as at I5 and I6 and I1 and I8.

Spaced inwardly from said beveled ends (the distance vdepending upon the gauge of the railway) are cut outs I9 and 20, and 2l and 22, to receive the iianges 23 and 24, of the rails 25 and 26. Seated beneath said cut outs are inverted U-shaped members 21 and 28, the side walls 29 and 3D of which are welded to the inner surfaces of the walls I3 and I4, and the tops 3| and 32, of which come iiush with the edges 33 and 34, of the cut outs and together with said edges form supports for the said rails.

Secured to the top of the members 21 and 28, by bolts 35, are chairs 36 and 31, the inner parts 38 and 39, seat upon the rail iiange 23, and abut the web 40, thereof. The bolts 35, are so located that their square beads 4I will abut the 2 walls 29 and 30, whereby they cannot turn; and the nuts 42, are secured by lock washers (not shown) and cotter pins 43. Apertures 44, are provided in the bottom wall I2, of the tie whereby they may be bolted to bridge work when necessary.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

Having now described my invention that which I claim to be new and desire to procure by Letters Patent is:

In a metallic railroad tie, the combination with rails, of a U-shaped metal tie comprising a bottom and side walls extending upwardly at right angles therefrom, the opposite ends of said side walls being downwardly and outwardly angled, the upper edges of said walls adjacent their opposite ends being formed with aligned notches having right angled side walls and being of a depth to receive the iianges of said rails for positioning the same, inverted U-shaped metal reinforcing members disposed in the opposite ends of said tie underlying the notches therein with the side walls thereof contacting the side walls of said tie and being welded thereto, the top surfaces of said inverted U-shaped metal reinforcing members extending ush with the bottoms of said notches in the tie and below the upper edges of said tie side walls, opposed angled rail chairs disposed on the opposite ends of said U-shaped .reinforcing members to overlie said rail flanges and extending flush with the upper edges of the tie side Walls, and chair securing bolts extending through said chairs and inverted U-shaped reinforcing members.
